BROODER STOVE.

Application filed. August 29, 1925. Serial No. 53,310.

The present invention relates to improvement in broeder stoves and itsparticular object isto provide a stove ot simple construction in which alarge heating surface is produced through direct contact with theproducts ot combustion and in which fresh air comes in contact with theother side of the heating surface and is discharged into the spaceprovided for the growing chicks without coming in Contact with theproducts ot combustion. A further object ot the invention is to insureperfect circulation of air whereby fresh air is continually drawn intothe heating chamber and discharged into the 7 space toward the burnersto provide a charge that is preheated and insures rapid and smokelesscombustion. i

It is further proposed in the present invention to provide a stove whichmay be readily taken apart and reassembled due to structural features ofthe same.

Further objects and advantages of my device will appear as thespecification proceeds.

The preferred form ot my invention is illustrated in the accompanyingdrawing which shows a vertical central section throughmy stove.

While I have shown only the preferred form of my device, it should beunderstood that changes or modications may be made within the scope ofthe claims without departing from the spirit of the invention.

Referring to the drawing in detail it will be noted that a tube 1 isinserted in a hole 2 in the floor 3 and held in place by means of aflanged collar 4. A plate 6 is telescoped over the upper end of the tubewhich plate is supported by means of a. rusto-conical wall 7 in spacedrelation to the floor 3 and so as to allow the tube 1 to project abovethe same. A tlange Son the plate leaves aspace between the flange andthe upper end of the tube in which is accommodated a seoond tube 9 inaxial alignment with the first tube while a fiange ll disposed near therim of the plate 6 allows a cylindrical wall 12 to be centered relativeto the plate and to be held in concentric relation relative to the tube9.y The Jfrusto-conical wall 7 is perforated as shown at 13 so as toallow air to pass therethrough from the outside and the plate 6 is alsoperforated as shown at 14 to allow the said air to rise toward theburnrounds the spreader and is similar in form but somewhat larger indimensions so as to be spaced from the spreader and to allow products ofcombustion to pass along the bottom of the spreader outwardly to turnaround the edge and move centerwise along the wall toward the top and tobe discharged into the stack 23. The bottom 24 ot the shell is formedwith a central hole 26 somewhat smaller than the wall 12 so as to allowthe bottom 24 to rest on the latter while a concentric ring 27 allowsthe shell to be centered relative to the cylinder 12. The spreader andthe shell are held in properly spaced relation by means of spacingelements 31.

The whole device is surmounted by the conical root 13 supported inspaced relation relativeto the shell by means .of spacing elements 32resting on smalllugs 33 projecting olutyardly from the bottom plate 24of the sie Short pieces of pipe 34 connect the inside of the spreaderwith the outside ot the shell so as to allow heated air to escape tromthe interior of the spreader' toward the root 18 without coming incontact with the products of combustion passing between the spreader andthe shell.

The operation of my stove may be readily understood from the foregoingdescription.

-When the burners 15 are lit air is drawn through the perforations 413oit the trustoconical wall 7 and the pertorations 1st of the. plate 6 tosupport combustion. The products of combustion rise between the tube 9and the cylinder 12 until they strike the bottom of the spreader 16.They are then deflected to assume radial direction while in intimatecontact with the spreader until they reach the edge of the bottom platewhereupon they again move centerwise in intimate Contact with thespreader and finally escape through the chimney 23.

The heating of the spreader causes air to rise therein and new air to bedrawn in from below the lioor 3 through the tubes 1 and 9. This new airis heated while rising,` through the two tubes and absorbs additionalunits while within the spreader 16 whereupon it is discharged throughthe pipes 34: into the space below the roof 1S whence it is deflecteddownwardly and discharged into the space immediately surrounding thestove and occupied by the chicks. This heated air again is drawn upon bythe burner in the manner previously described so that constantcirculation is kept up and the chicks are provided with a. continuoussupply o1c fresh and heated air.

Haring; described m3.' invention what I claim isz l. ln a broederstove,` a vertical tube, a spreader having a tlal bottoni and a conicaltop communicating with the upper end ot the lube` a burner surroundingthe latter, means surrounding the burner and the spreader allowing airto enter below the burner a nd guidingA the products ot combustion.around the spreader in intimate contact therewith tor discharge abovelhc spreader and means allowing air entering through the tube into thespreader to escape through the top thereof without coming in contactwith the products ol combustion.
